In the context of Soil erosion, consider the following statements:
Which of the above statements are correct?
Solution (a)
Explanation:
Statement 1 is incorrect: Terrace cultivation is one of the methods for soil conservation. Terracing is a soil conservation practice applied to prevent rainfall runoff on sloping land from accumulating and causing serious erosion. Terraces consist of ridges and channels constructed across the slope.
Statement 2 is correct: In eluviation, when rainfall surpasses evaporation, dissolved or suspended material is removed from a layer or layers of soil by water movement. Illuviation involves the deposition of these nutrients and organic materials in deeper horizons, forming horizons in organic materials.
Statement 3 is correct: Different trials with pigeon peas for preserving the topsoil have been successful because of their vigorous and rapid canopy development. The soft soil and high soil moisture on the riverbanks help the pigeon pea plants in developing strong and deep root systems which help in holding the soil together.
Statement 4 is correct: Rill erosion is a type of erosion that produces small but distinct streams. It occurs when rainwater does not soak into the soil but instead runs across it. Rill erosion is removal of soil by concentrated water flow, and it occurs when the water forms small channels in the soil as it flows off site. The rills or small channels (often only 30cm deep) form when water flowing across the ground collects in a natural depression in the soil and erosion is concentrated as the water flows through the depression.

Consider the following statements about the Black soil:
Statement-I: Black soil has a characteristic of self-ploughing.
Statement-II: Black soil has a high-water retention capacity.
Which one of the following is correct in respect of the above statements?
Solution (a)
Explanation:
Black soil is the third most common type of soil in India. The name “black soil” comes from the color of the soil, which is black. It is most suited for cotton cultivation, as well as groundnut, sugarcane, tobacco, wheat, millets, and oilseeds.
Statement I is correct. Black soil is also referred to as Self-ploughing soil. Self-ploughing soil is simple to cultivate. Soil that can retain or absorb water and expands as a result of moisture accumulation. Such soil necessitates a significant amount of labor during the wet season.
Statement II is correct and the correct explanation of Statement I. Black soil is high in potassium, magnesium, calcium carbonate, and lime but low in nitrogen and phosphorus.
Because of these features, ploughing the soil gets easier, or we may say it is self-ploughing. As a result, black soil is also known as self-ploughing soil.

Which of the following are the features of the Intensive subsistence farming?
Select the correct answer using the codes given below:
Solution (b)
Explanation:
Intensive-subsistence farming mainly results from a single cause of limited land. And as land is passed on from one generation to the next, it is fragmented into smaller plots to divide among the offspring of the farmers. So, it goes on getting smaller and smaller until it cannot produce enough to even satisfy the needs of a single family and the farmer uses intensive practices to fulfil production.
Statement 1 is incorrect: The small size of the landholdings (and not large size of the landholdings) of the farmers is the primary feature of the intensive-subsistence agricultural system. Commercial farming involves farming a single crop over the entire piece of land for the commercial purpose for say imports and exports of the crops. Thus, commercial farming has the feature of large landholdings.
Statement 2 is correct: The use of animal and plant manures as a characteristic of intensive-subsistence agriculture is also related to the lack of money to afford chemical or artificial fertilizers by the farmer. But this is a good thing since bio-fertilizers made from kitchen waste, human excreta, farm waste, plants, and animal dung doesn’t affect the soil and the environment. So, this is one of the good aspects of this form of farming practice since even though it puts pressure on the soil and land, the addition of nutrients in the form of manures and bio-fertilizers tries to balance it out.
Statement 3 is correct: Paddy is the most grown crop in the intensive-subsistence agricultural system and several other food crops are also extensively grown and they vary according to location and its climate, soil, and topography. For example, wheat, soybeans, and barley are majorly grown intensively in subsistence farms of northern parts of China, Japan, and Korea and also parts of India like Punjab. In areas where rainfall is not adequate, food crops like millet and sorghum are grown. Maize is also often included in the crop rotation at one time of the year. Peas and other vegetables are often integrated with plants like maize.

Why are the floodplains ideal location to develop the urban areas?
Select the correct answer using the code given below:
Solution (a)
Explanation:
A floodplain (or floodplain) is a generally flat area of land next to a river or stream. It stretches from the banks of the river to the outer edges of the valley. Floods are usually seasonal and can be predicted months ahead of time. This predictability can make floodplains ideal locations to develop urban areas.
Option 1 is correct. Harvesting water from floodplains is a source of water for urban regions across the country and can be used as a regular and a contingency water reserve.
Option 2 is incorrect. Floodplains are usually very fertile agricultural areas. Floods carry nutrient-rich silt and sediment, and distribute it across a wide area. Floodplains are flat and often have relatively few boulders or other large obstacles that may prevent farming. The relatively level land can be developed either as agricultural fields or sites for habitation or business.
Option 3 is correct. A floodplain’s flat terrain and slow-flowing rivers can provide excellent transportation corridors. Roads, bridges, railways, and even airports can be constructed on the even surface. Ships and barges can often haul cargo faster and more efficiently than roadways. Rivers provide both a natural transportation network and source of water for irrigation and industry.
Option 4 is incorrect. Floodplains have dazzling arrays of biodiversity. These seasonal riparian wetlands boast greater biodiversity than the rivers themselves. The floodplains of Congo River tributaries, for instance, boast one of the most unusual fish on the planet: the West African lungfish.

Which of the following is/are the advantage/advantages from zero tillage farming?
Select the correct answer using the code given below:
Solution (d)
Explanation:
Zero tillage farming (no till farming) is an agricultural technique for growing crops or pasture without disturbing the soil through tillage. No-till farming decreases the amount of soil erosion tillage causes in certain soils, especially in sandy and dry soils on sloping terrain
Option 1 is correct. The zero-tillage system is being followed in the Indo-Gangetic plains where rice-wheat cropping is present. Wheat will be planted after rice harvest without any operation. Hundreds of farmers are following the same system and getting more yields and profits by reducing the cost of cultivation. Reduction in the cost of inputs for land preparation, reduce labour, machinery cost and irrigation and therefore it saves around 80% of the cost.
Option 2 is correct. The presence of mulching also helps to reduce the surface runoff which keeps soil moisturized and helps to keep nutrients intact. Residual moisture can be effectively utilized and number of irrigation’s can be reduced.
Option 3 is correct. The organic matter content of the soil is increased through the decomposition of roots and the contribution of vegetative residues on the surface. This organic material decomposes slowly, and thus the liberation of Carbon to the atmosphere also occurs slowly and it helps to increase the organic content in the soil.
Option 4 is correct. No tillage reduces the compaction of the soil and reduces the water loss by runoff and prevent soil erosion. As the soil is intact and no disturbance is done, No Till lands have more useful flora and fauna.

With reference to the benefits of rainwater harvesting, consider the following statements:
How many of the statements given above are correct?
Solution (c)
Explanation:
Rainwater harvesting is a method to capture and store rainwater for various uses. It is also
used to recharge groundwater aquifers. It is a low cost and eco-friendly technique for preserving every drop of water by guiding the rain water to bore wells, pits and wells.
Statement 1 is correct: Rainwater harvesting helps reduce soil erosion by capturing rainwater and preventing it from flowing over the surface and eroding topsoil.
Statement 2 is correct: In rainwater harvesting involves the process of collecting rainwater and directing it underground. When rainwater is collected and directed into the ground through methods like percolation pits or recharge wells, it replenishes the groundwater reserves. This helps maintain a higher water table, which acts as a barrier against the encroachment of saltwater.
Statement 3 is correct: Rainwater harvesting contributes to the augmentation of groundwater by storing rainwater for future use, which can then percolate into the ground, replenishing aquifers. This increasing level of groundwater table enables farmers to pump out groundwater using less electricity.
Statement 4 is incorrect: Rainwater harvesting is typically suitable for household or small-scale agricultural use. It may not provide a sufficient supply for large-scale industrial or agricultural operations as it depends on factors such as storage capacity of rainwater harvesting plant, requirement of industries etc. Hence the statement that rainwater harvesting essentially ensures sufficient supply of water of large-scale industrial usage is incorrect.

Explanation:
The Public Stockholding (PSH) program, a crucial element for India’s food security, faces challenges under WTO rules. India’s minimum support prices (MSP) and procurement quantities for staples like rice and wheat often exceed permissible limits, triggering concerns. Data indicates that a significant percentage of India’s population depends on agriculture for livelihood, making food security a paramount concern. However, the clash between India’s domestic support programs and WTO norms creates tension. The need to uplift millions from poverty and hunger clashes with the demands of international trade agreements. Rising population pressure and the unpredictability of climate change underscore the urgency of ensuring food security.
Explanation
Option (a) is incorrect: The passage is on the clashes between India’s food security concerns and WTO norms. The given option means that India does not adhere to international trade norms, which is not reflected in the passage. Also, reforming agricultural laws and policies is not the core idea of the passage. Hence, this option is incorrect.
Option (b) is incorrect: The given option is extreme and is not based on the passage. The passage shows the concerns that India faces in food security by following WTO norms. The author nowhere hints towards leaving WTO. The main theme of the passage is that it is difficult to balance both aspects. So, this is not the correct option.
Option (c) is incorrect: Whether WTO norms are discriminatory is not mentioned in the passage. Also, how those discriminatory norms restrict India’s commitment to food security is not mentioned in the passage. So, this option is beyond the scope of the passage and is, therefore, incorrect.
Option (d) is correct: The central theme of the passage is the challenges India faces in ensuring food security in the backdrop of WTO norms. This is reflected in the lines “However, the clash between India’s domestic support programs and WTO norms creates tension. The need to uplift millions from poverty and hunger clashes with the demands of international trade agreements.” This option captures this theme comprehensively.

Implementing measures to reduce greenhouse gas emissions, transition to renewable energy sources, and enhancing climate resilience necessitate financial investments. These costs encompass not only the deployment of clean technologies but also the restructuring of industries, the development of sustainable infrastructure, and the adoption of climatesmart agricultural practices. Moreover, the economic impact extends beyond direct expenses. Industries relying on fossil fuels may face restructuring costs, and regions vulnerable to climate impacts may bear the economic burden of adapting to changing conditions. However, the cost of inaction far exceeds the investment required for climate mitigation and adaptation. Ultimately, viewing the costs of climate action as an investment in a sustainable and resilient future underscores the importance of proactive measures.
Explanation
So, this option is beyond the scope of the passage and is not the most rational inference.
Option (b) is correct: The main issue in fighting climate change as per the passage is funding as seen in the lines “Implementing measures to reduce greenhouse gas emissions, transition to renewable energy sources, and enhancing climate resilience necessitate financial investments” and “Ultimately, viewing the costs of climate action as an investment in a sustainable and resilient future underscores the importance of proactive measures.” Therefore, we can infer that when cost is central to fighting climate change, then without funding and proactive measures, almost everyone will face the brunt of climate change. These arguments are aptly captured in this answer option.
Option (c) is incorrect: The main theme of the passage is the core issue of funding which is essential to fighting climate change. Mitigation and adaptation measures are only a part of the passage and not the central theme of the passage. So, this option is not at all the most rational inference.
Option (d) is incorrect: The given option is quite broad, generic, vague and not quite specific to the information contained in the passage. The passage primarily discusses the issues of funding in every aspect of fighting climate change. This is not captured in this answer option. So, this option is not the most rational inference of the passage.
